Bonavita Lid Cap Replacement

It's a shame it's not easier to get Bonavita replacement parts when life happens. An otherwise perfectly good lid kept falling apart after a visiting dog chewed the cap off. So I made one to twist on!

The geometry of the lid internals isn't symmetric. I tried and failed to make a snap-on latch based lid. However, the twist lid worked first try! About $0.50 plastic instead of buying a $40 coffee carafe to get a new lid.

The model is tuned for PLA and the following print settings on a Kobra3v2. The model design should tolerate a little variation and still function.

Print Settings--I used the LowRiderV4 advice as a basis:

• PLA for rigidity

• 0.4mm nozzle

• 0.2mm high quality profile as basis:

  • 4 wall loops

  • Rectilinear top and bottom surface patterns

  • 5 top and bottom shell layers

  • cubic infill pattern at 15%

  • Line width of 133% for all but supports

  • Supports enabled

Assembly:
  Align the large gaps with the spout and lever. There's only one proper orientation-- The small indent in the lid clears the rib on the lever side of the cap. Slide in, press, and twist until the tabs engage the ramps in the cap.
